Practical guidance
Fleet and rental comparisons
Rental cars and fleet vehicles may be rated in either system. Converting lets you compare fuel costs accurately before booking or purchasing.
What good numbers look like
Under 5 L/100km (over 47 MPG) is excellent. 5–8 L/100km (29–47 MPG) is good. Over 10 L/100km (under 23.5 MPG) is below average for modern passenger vehicles.
Mistake: comparing without converting
A car rated at 25 MPG and another at 10 L/100km may seem different, but they are nearly identical in efficiency. Always convert before comparing.
